Principles of Spectrophotometry ... A spectrophotometer consists of two instruments, namely a spectrometer for producing light of any selected color (wavelength), and a photometer for measuring the intensity of light. The instruments are arranged so that liquid in a cuvette can be placed between the spectrometer beam and...

Spectrophotometry is the quantitative measurement of the reflection or transmission properties of a material as a function of wavelength. While relatively simple in concept, determining the reflectance or transmittance involves careful consideration of the geometrical and spectral conditions of the measurement.

Because all solutions of chemical compounds absorb light of specific wavelengths, spectrophotometry can be useful in identifying compounds. Furthermore, because the amount of light absorbed is proportional to the concentration of a compound, spectrophotometry is also useful in determining concentrations.
